“…The absence of an effect of pregnancy on HPV infection is also supported by the observation that HPV positive rates were similar across gestational stages. Although some studies have reported an increase in HPV prevalence with gestation [Czegledy et al, 1989;Rando et al, 1989;Smith et al, 1991], reports from Hording et al [1990], Chang-Claude et al [1996] and Fife et al [1999], were in accord with the present findings. It has been shown that the number of sexual partners is the most important variable affecting the risk for HPV infection [Rohan et al, 1991;Munoz et al, 1996;Tortolero-Luna, 1999].…”

“…Most of the available data on HPV prevalence among pregnant women are derived from studies based on hybridization techniques that are suboptimal in sensitivity, and the spectrum of HPV detection is often limited to a few common genotypes [Fife et al, 1987[Fife et al, , 1996[Fife et al, , 1999Schneider et al, 1987;Rando et al, 1989;Hording et al, 1990;Chang-Claude et al, 1996;Morrison et al, 1996;Armbruster-Moraes et al, 2000]. In this study, the association between pregnancy and HPV prevalence was examined using the most sensitive catch-all detection method, consensus primer-based polymerase chain reaction (PCR), followed by an identification system that covers all the known genotypes.…”

Controversies exist on the effect of pregnancy on human papillomavirus (HPV) infection. A cross-sectional section study was conducted to compare the prevalence and genotype distribution of cervical HPV infection between pregnant and non-pregnant women in Hong Kong. Cervical samples were collected from 308 pregnant women and from the same number of age-matched controls recruited from a cervical cancer screening center located at the same hospital. HPV was detected by the polymerase chain reaction, followed by genotype identification by restriction fragment length polymorphism and direct sequencing analyses. The prevalence of HPV for pregnant women was 10.1%, without significant variation with age, gestation, gravidity and parity. The prevalence of HPV for non-pregnant group was 11.4% and did not show significant difference when compared to the pregnant group either by overall or age-stratified subgroup analyses. When the analysis was stratified according to the risk-type of HPV infection, still no significant difference between pregnant and non-pregnant groups was observed (all types: 10.1 vs. 11.4%, P = 0.602; high-risk types: 5.8 vs. 7.8%, P = 0.338; low-risk types: 1.0 vs. 2.9%, P = 0.080; unknown-risk types: 3.2% vs. 1.3%, P = 0.105). The results of this study show no evidence for an influence of pregnancy on HPV prevalence, and a majority of HPV-infected pregnant women had normal cervical cytology. HPV positive results in pregnant women per se should be managed conservatively.

“…The existence of HPV DNA in the genital tract of adult women has been reported in many studies. In a Danish study HPV DNA was found in 8.7 percent of 1,362 pregnant women whereas HPV DNA was found in 53 percent of a 'non-high risk population' of 13 1 women attending a family planning clinic in England (23,24). The large difference could probably partly be explained by different methods of selection and analysis.…”

The authors present a study of five cases of vulvar congenital papillomas and papillomatoses in stillborns and neonates dead upon birth. The studied material was collected from five necropsies. The histopathological evaluation showed hyperkeratosis, acanthosis, papillomatosis, perinuclear haloes, and nuclear abnormalities. In three of the cases, the electron microscopy identified nuclear and cytoplasmatic viral particles ranging from 40 to 60 nm in size, compatible with HPV. The immunohistochemical study of those lesions showed nuclear and cytoplasmatic positivity. The authors concluded that the presence of viral particles suggestive of HPV added to the immunopositivity indicated the possibility of viral infection.
